Unlike earlier systems that had a limited number of measuring channels and as a result were only able to guarantee a maximum board coverage of 30%, this system is able to detect defects over the whole board. It is possible to grade the quality of the production in progress and to adjust product parameter to avoid rejects and maximize customer satisfaction. The system is composed of a sturdy beam, installed around the conveyor, complete with the electrical and pneumatic plant. It is possible to slide the bottom part of the system out to perform maintenance or repair without the need to stop production. The full bond/blister classifier (FBC) measuring sensors are mounted on the top and bottom beams on the board outfeed side. Since the sensors do not come into direct contact with the board, typical problems related to material wear are eliminated. In addition, when the system is installed at press outfeed, a pressurization unit is normally supplied which is mounted on the top of the beam to prevent the sensors from being damaged by the vapours released by the upper surface of the board. The automatic calibration and dirt accumulation control ensure an efficient and highly reliable measuring control system. The operator interface for setting up the plant parameters and those for the single productions is simple and straightforward to use and the formulas may be stored and retrieved at a later date. The display can be customised by choosing from the numerous high resolution 3D colour graphs available. Numerical indications are also given. The parameters are stored in an SQL database and can be used to display and/or print reports on the desired productions, based on user determined choice criteria (date of production, shift, production name). In addition to being user friendly and extremely intuitive to consent a prompt and immediate interpretation of the data collected, the software also provides detailed diagnostic screen pages to enable maintenance operators or Imal engineers carrying out remote assistance, to perform a full diagnosis of the equipment. A powerful microcontroller is mounted inside the receiver to transmit the data for the signal measured, to the CPU via Data Bus. The system may be network connected with TCP/IP protocols, for Siemens S7 and Allen-Bradley ControlLogix.
